Abstract
This study carried out the experiment, which removed Carbon Dioxide and nitrogen, phosphorus using minute algae cultivated high-density. The environment of microalgae pH showed alkalinity and ORP showed the reduction area of 247-44OmV. The nitrogen rejection ratio by microalgae was 71%. The low extraction ratio in this result was nitrate nitrogen. And, the phosphate elimination rate was good with 74%. It was more possible to obtain basic data, which effectively remove Carbon Dioxide, nitrogen and phosphorus using microalgae than the above result.
